-------------------------------------
Summary: Enable caching of side-input dependent computations
Key: BEAM-1002
URL: https://issues.apache.org/jira/browse/BEAM-1002
Project: Beam
Issue Type: New Feature
Components: beam-model
Reporter: Robert Bradshaw
Assignee: Frances Perry
Sometimes the kind of computations one wants to perform in startBundle depend
on side inputs (and, implicitly, the window). For example, one might want to
initialize a (non-serializable) stateful object. In particular, this leads to
users incorrectly (in the case of triggered or non-globally-windowed side
inputs) memoizing this computation in the first processElement call.
One option would be to fold this into a customizable ViewFn.
